NONDESTRUCTIVE TEST EQUIPMENT EMPLOYING SQUID MAGNETIC SENSOR |
摘要 |
<p>There is provided a nondestructive inspection apparatus using a SQUID magnetic sensor which allows nondestructive and accurate detection of magnetic particles in an insulator such as an electronic device or in a magnetizable member. The nondestructive inspection apparatus using the SQUID magnetic sensor comprises: a magnet for horizontal magnetization 4, the magnet applying a magnetic field to a specimen in the longitudinal direction of the specimen 3'; an inspection unit on which a specimen 3 is set, the specimen 3 being horizontally magnetized in the longitudinal direction by the magnet for horizontal magnetization 4; and belt conveyers 2, 5 for conveying the horizontally magnetized specimen 3; and a gradiometer 8 for detecting a particle horizontally magnetized along with a magnetizable member as the horizontally magnetized specimen 3.</p> |
